"Do I have to have more Pokémon in order to battle better? No! I'm sticking with this one no matter what! Listen, can I get your phone number? I'll ring you for some battles. I'm a rookie too, so I think it'd be a good motivator."

No: "Oh, all right... But I won't lose to you again!"

If talked to again

"Can I get your phone number? I don't want to lose against you! We have to battle again, OK?"

Yes: "I'll ring you whenever I get the urge to battle!"/"Huh, what? Your phone's full."

Calling the player

"Yo, <player>! How're you doing? This is Joey, got a minute?"

"Yo, <player>! How's it going? This is Joey. Got a minute?"

"How are your Pokémon doing? My Rattata's looking sharper than before! I doubt there's a Pokémon as cool as this guy in your party!"

"How are your Pokémon doing? My Rattata's raring to go, just like always. It's the only one I have. I'm going to become a great trainer with it!"

"Oh yeah, I saw a wild <Pokémon>! I thought about going for it, but I decided to work with my one-and-only right to the extreme end."

"Oh yeah, I took down a <Pokémon> in the wild the other day. It was a cakewalk. Well, I guess it can't be helped, us being so tough."

"My Rattata's looking awesome! I wish I could show you. Hey, listen! I almost caught Pokémon the other day. Oh, it was soooo close too! See you later!"

"Let's get together and battle! I promise things will be different! Route 30's where I'll be. Give me a shout when you come. All right. Later!"

History

Gold then decides to retrieve the stolen objects. He soon succeeds and catches the Murkrow. The boys soon become friends.

After the incident with Murkrow, Gold and Joey travel together for a while. After a trip in New Bark Town, Gold notices Pokémon from his backpack have been stolen and they go to the laboratory to tell Professor Elm about it. Unfortunately, they come to the lab just after Silver stole the Totodile. After that, Joey uses his computer to montage a picture of Silver for the police. Then, they meet Professor Oak who is interested by the fact that Silver had a Pokédex. It turns out that Oak was the one who ordered him to deliver the Pokémon to Elm. Gold wants to get a Pokédex from Professor Oak, but the professor refuses.
